I have a B450 Tomahawk, Ryzen 5 2600 and Corsair Vengeance DDR4 LPX 16GB 3200Mhz.
I was previously running bios version 7C02v15 (aPre zen 2 bios), and with XMP enabled my ram ran at the correct frequency of 3200 Mhz.
However, I today purchased a Ryzen 3700x, and before installing the new processor updated the motherboard bios to the latest version (7C02v1A), which is compatible with the new gen 3 ryzen processors.
The latest bios has updated the bios to a new version which is called Click BIOS (GSE-Lite), and the settings are slightly different, including XMP (so this may well be the crux of my issue, but I'm pretty sure I'm doing it right... or at least it used to work buy clicking the XMP button).
The problem that I am having is that the RAM is not running at the correct frequency, no matter whether I leave A-XMP disabled, or set it to profile 1, or profile 2.
Both profiles are displayed as 3200Mhz in bios. However, when I boot into windows 10, CPU-Z shows completely the wrong ram frequency.
I tried the second latest BIOS (7C02v19) and I'm still having the same issue.
----------
I have since installed the 3700x with the latest 7C02v15 bios, installed the latest ryzen master and chipset drivers etc, but the ram still doesn't display as 3200Mhz. CPU-Z currently displays dram frequency as 1599.6 Mhz.
I have attached a screenshot of CPU-Z.
Any help is much appreciated. Thanks
